7 The "Winter in Frejus" release. Also known as "ANR/ADT funding helps"
10 * New feature: Model check any simgrid simulation
11 * SMPI: now considered stable
13 - now covers the whole framework
14 - major usability improvements
16 - scalable platform management through hiearchical description
17 - new efficient way to bypass the XML parser
18 * MSG: at last asynchronous functions are available
19 * SIMDAG: many usability improvements (dotloader, ...)
20 * GRAS: finally catch up with latest internal evolutions
22 - Windows port: should be usable now but still considered experimental
23 - Autotools have now been completely removed

56 The "Desktop Grid needs love too" release (also called "Xmas release").
57 Most important changes:
58 * Big speedup through lazy evaluation of the linear models
59 * Supernovae mode: Compile everything in one unit to improve inlining
60 * Simix network module for internal cleanups
61 * Load DAX of applications into SimDag
62 * Lot of small cleanups and other bug fixes

79 The "Simplicity does not preceed complexity, but follows it" release.
80 Most important changes:
81 * surf and simix modules reworked for simplification.
82 It lays the ground for future extensions and improvements of SimGrid
83 * SMPI was further improved, altrough not ready for production use yet.
85 On the way, we gained a bit more than 5% on the classical master/slave
86 example. More to come on this in future releases.

94 This dot release is mainly a maintainance one. Most important changes:
95 * We fixed a large amount of bugs all around
97 * We sanitized the way configuration is handled internally.
98 Try passing --cfg-help to binaries compiled against this version.
100 * SMPI is in better shape: lot of bugs fixing & usability improvements
101 It may be worth trying it (even if all bugs are not gone yet)
103 This version may have a bit more of memleaks than 3.3. This will be
104 fixed in a latter release.

126 At least, after 2 years of hard work, we managed to release the 3.3
127 version of the SimGrid framework. There is so many changes that the
128 changelog only lists the most important ones, leaving alone the small
129 improvements, bug fixing and new gadgets.
133 * New simulation models, and improvement of the GTNetS wrapper
135 * Large memory savings (mainly in parser)
136 * Faster (twice faster is not uncommon, and from 20 hours to 2
137 minutes on very large scenarios)
138 * Much better scalability (tested up to 250,000 processes)
140 * Complete regression testing framework so that you can trust the tool
141 * Lot of neat new modules in the XBT toolbox
143 This version was throughfully tested on linux 32bits and 64bits
144 (debian), as well as Mac OSX (leopard).
146 Unfortunately, our windows-guy left, and we cannot release the windows
147 version at the same time than the other archs. Any help would be
148 really welcomed here.
150 Some of the 96 included test suites are known to fail, but everything
151 should work anyway (don't panic):
152 * The amok module does not work in real deployment ATM, but I don't
153 see this as release critical since I'm not aware of anyone needing
155 * Some tests about the ability of GRAS to receive messages from
156 exotic platforms fail because I've lost access to these platforms
158 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
159 quite puzzled, but I suspect a bug in the test, not in the lib.
160 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
161 sometimes too verbose (when the OS creates hidden files, I
162 suspect), but tesh definitly work as the rest on this arch.
164 We hope to manage to do more timely releases in the future, even if
165 that may turn out difficult since big stuff is comming (I don't say
166 much here for the suspense ;)
168 We hope you'll enjoy this new version, and please report any feedback
169 on the <simgrid-user@lists.gforge.inria.fr> list.
